Inventor: LEE YOUNG HEE
IPC: F26B3/347
Filed: 2001-11-26
Granted: 2005-06-21
Abstract: The apparatus for uniformly dispersing the microwave comprises a body including a plurality of reflective portions which are made of materials capable of reflecting the microwave and have the horizontal top surfaces and vertical side surfaces. The width of the plurality of reflective portions is set as 1/n times as large as a wavelength .lambda., g of the microwave. The depth of each of the plurality of reflective portions may be set as a value obtained by multiplying the remainder, which is obtained by dividing the power of a natural number for the least primitive root of a prime number by the prime number, by the width of the reflective portion under a condition that a datum plane is defined by a height from the bottom surface corresponding to a value obtained by multiplying the width of the reflective portion by (prime number -1).

Abstract: A fluid transmitting device includes a side cover connected to a pump impeller and defining a clutch chamber between the side cover and an outer surface of a turbine runner, and a lock-up clutch which includes a clutch piston connected to the turbine runner. The clutch chamber is divided by the clutch piston into an inner oil chamber and an outer oil chamber.      In the fluid transmitting device, a dividing means for dividing the inner oil chamber into a primary inner oil chamber section and a secondary inner oil chamber section is provided between the turbine runner and the clutch piston. When a lock-up control device is operated to urge the clutch piston in a clutch switch-on direction, the pressures in the primary inner oil chamber section and the secondary inner oil chamber section are raised in the named order relative to the outer oil chamber.  Thus, the connection responsiveness of the lock-up clutch can be enhanced in a simple structure.

Abstract: Handling of liquid containers in horizontal position in the form of beverage packaging, for example, cans or or bottles of any cross-section, comprising a first and a second conveyor with respective belt, especially in connection with detection of features of the container. The belts are movable in a mutually parallel direction, and in a first, container-supporting position form an angle relative to each other, thereby forming an approximately V-shaped conveyor. The two conveyors can be moved apart to a second position thereof, thereby exposing in the space between the conveyor belts a pair of rotary rollers which have the same direction of rotation and having their axis of rotation in the direction of travel of the conveyor belts, whereby a container that is supported by the conveyor belts falls onto the pair of rollers and is rotated there in order to detect with the aid of a detector unit characteristic features of the container, for example, its contour, an identification code or the like, and means for moving the two conveyor belts from the second position back to the first position, whereby a container that is rotated on the rollers is lifted up and away from the rollers by the conveyor belts for support by the conveyor belts in said first position. The container may in said first position of the conveyors be caused either to be carried onwards to a point downstream in relation to the conveyors or be carried back to an upstream position.

Granted: 2008-04-08
Abstract: The invention relates to a method for operating a heat-producing plant having a chamber (2) for burning chlorine-containing fuels and a channel (3) connected with said chamber, in which a plurality of consecutive heat- transferring devices (5, 5', 5") are located, which can heated by hot flue gas which flows through the channel in the direction from the combustion chamber (2) towards an outlet (4).

By means of the additive, alkaline chlorides in the flue gas is sulphated, with the aim of reducing chlorine-induced corrosion of the heat-transferring devices. As additive, a compound chosen from the group: ammonium sulphate ((NH4)2SO4), ammonium bisulphate ((NH4)HSO4), ferrous sulphate (FeSO4), and sulphuric acid (H2SO4), is used, in order to form reactive sulphur trioxide (SO3) at the occasion of entrance, which is added in a quantity of at least 20 mg S/m3n (normal cubic metres) flue gas.

Title: Film fracture feature for peelable multilayer package lid
Inventor: BARMORE CHARLES RICE
IPC: B65D43/02
Filed: 2003-12-18
Granted: 2007-02-13
Abstract: A package for storing and shipping food products incorporates a multilayer film lid that includes a gas-impermeable exterior layer and a gas-permeable interior layer. The multilayer film lid is heat sealed to a flange of a tray upon which the food product is supported. The gas-impermeable layer may be delaminated from the gas-permeable layer when it is desired to expose the food to atmospheric gases. Separation of the gas-impermeable layer from the gas-permeable layer is facilitated by a film fracture feature included in the heat seal pattern adjacent a pull tab of the lid. The film fracture feature concentrates the separation forces exerted on the tab in a small area so that the gas-permeable layer of the lid readily breaks at the film fracture feature.

Title: Valve gated injection molding system with independent flow control
Inventor: BABIN DENIS
IPC: B29C45/30
Filed: 2004-02-13
Granted: 2011-11-22
Abstract: An injection molding system includes a manifold and a valve gated hot runner nozzle. The gating mechanism includes an actuated valve pin, where the mold gate orifice is open when the valve pin is in a first position to allow melt to flow there through. The mold gate orifice is closed when the valve pin is in a second position to prevent melt from flowing there though. A flow control pin is disposed within the melt stream, either coaxially with the valve pin within the melt channel of the nozzle or within the manifold melt channel. The flow control pin has a head with a complementary geometry with that of the melt channel at a flow control surface. The flow control pin is raised and lowered by an actuation mechanism to constrict or release the flow of the melt stream independent from the movement of the valve pin.
